DIAL-FASTENING DEVICE FOR WATCHES.

To all whom it may concern:

Be it known that 1, WILLIAM B. MILLER, a citizen of the United States, and resident of Louisville, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Dial-Fastening Devices for Watches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in dial fastening devices for watches, the objects of the same being to provide devices which will properly secure the dial in proper engagement with the watch-plate. The fastening devices being of such construction that they will hold the dial in close engagement and in proper engagement with the watch plate.

Another object of the present invention is to so construct the part-s that an ordinary watch plate can be employed in connecting the various parts designed to hold the dial.

These objects together with other objects readily apparent to those skilled in the art I attain by the construction illustrated in the accompanying drawing, although my invention may be embodied in a variety of other mechanical forms, the construction illustrated being chosen by way of example.

In the accompanying drawing-Figure 1 is a view showing the back or underside of the watch plate showing a part broken away and illustrating one set of the watch dial connecting parts. Fig. 2 is an edge View of the watch dial. Fig. 3 is an edge view of the dial and watch-plate, showing the same properly connected together. Fig. 4 is a fragmentary perspective view of the dial and watch plate showing said parts detached from each other. Fig. 5 is a fragmentary view of the watch plate showing the dial holding devices in position to disconnect the dial from the watch plate.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the watch-plate, which is constructed in the ordinary manner, reference being had to the proper connection and location of the Specification of Letters Patent.

the watch-plate, thereby constituting chambers, in which chambers are located the dial securing pawls 5, whichpawls are formed of a thickness to properly fit the kerfs or chambers 4, and to so fit that there can be no springing of the pawls when they are brought into proper position to secure the watch-dial. In order to secure accuracy it is preferable to first form the apertures 6 in the watch plate 1 and afterward cut the kerfs and extend the kerfs or cut the kerfs to a depth sufficient to bring the inner wall of the kerf substantially diametrically across the apertures 6 and after thus cutting the kerfs the dial can be placed in position entering the studs 3 in the apertures 6 and cutting the notches 7 to a depth corresponding with the depth of the kerfs, by which arrangement the seats of the notches 7 are in true alinement with the seats or back By thus forming the kerfs and notches 7 a perfect fit and a snug fit can be brought about when the pawls 5 are brought into position to lock the dial upon the watch plate.

It will be understood that when the watch plate is placed in proper position with reference to the watch case, the pawls will be held against outward movement, thereby preventing any disengagement of the pawls from the dial connecting studs.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is r In a dial fastening device for watches, the combination of a watch-plate, said plate provided with a series of kerfs, said kerfs located in the body of the watch-plate, the watch-plate provided with a series of apertures, said apertures located at a point to be cut diametrically by the kerfs, a dial-, plate provided with a series of studs, said.

studs provided with notches and the seats of the notches located in alinement with the back walls ef the kerfs, a series of pawls In testimony that I claim the above, I located Within the kerfs and normally Withhave hereunto subscribed my name in the in the body of the watch-plate, said pawls presence of two Witnesses.
